Home Drive allows you to upload and download files to and from a WebDAV destination using the 'Open In' feature found in several apps.
Currently supported document types are:
Pages, Numbers, Keynote, Word, Excel, Powerpoint, text, rich text, images, audio and video. If you come across an unsupported type, email firstname.lastname@example.org with details and I'll add it as soon as possible.
We use it at my school on our trolley of shared iPads and our staff devices to connect to our SharePoint. Once configured, it’s a very simple app - if you use ‘Open In’ from any app that supports it and select Home Drive, the file is transferred. You may also choose an item from the camera roll to upload, or browse for files to download - these will be previewed in the app and can then be opened in other apps that support them.
The app can be configured in single user mode (one webdav destination and username/password) or in multi-user mode where the webdav root is set and the final path is derived from the username, which will be prompted for each time the app is used.
The app can be configured from a URL or via a smart banner, and supports running a pre-flight script (set by you, on your own server) every time the a new user signs in.
